And as I proved, indexing content doesn’t always mean crawling JavaScript-generated links. Google managed to index only a few out of multiple JavaScript frameworks tested. The results were shocking it turns out Google has a number of problems when crawling and indexing JavaScript-rich websites. Here we discuss the introduction to JavaScript find() and its different parameters along with examples.I recently published the results of my JavaScript SEO experiment where I checked which JavaScript frameworks are properly crawled and indexed by Google. The javascript is a built-in function of javascript, which is used to identify the first element of an array that satisfied the specified testing function. Next example code where the javascript find() method is used to find the prime number, as in the below code.īelow is the first prime number of an array which satified the condition element % first++ ĭocument.writeln(.find(isPrime)) However, as in array, none of the elements is even. In the above code, an array is created of and applied the find() method to check whether the number is Even or not. In the next example code, we rewrite the above code for the javascript find() method to apply on an array whose none of the elements satisfied the condition for an even number. In the above code, an array is created of and applied the find() method where it accepted the function that is isEven(), which checks the condition element%2 = 0 ( condition for even number) on each element of an array, so in an array 20 is the first element who satisfied the condition. Next example code where the javascript find() method accepts a name of the function to check the condition on each element of an array, as in the below code.īelow is the first even number of an array which satified the condition element%2 = 0. Example #2Įxample of javascript finds () method with function. In the above code, an array is created of, and the find() method is used where the specified condition x>30, so in an array, 40 is the first element that satisfied the condition. Below is the first element of an array which satified the condtion = >30. This is an example for find function in JavaScript Next, we write the html code to understand the javascript find() method more clearly with the following example, the find() method used to return the first element of an array that satisfied the condition, where here we will pass the condition directly without using the function.
